Addicted To Boost Posted April 27, 2009 Report Share Posted April 27, 2009 Are both of your injector fuses good? If you mean the small 15-20amp fuses, then yes, we've checked and replaced them. Yep, thats what I was talking about, two 20 amp fuses IIRC. Quote Link to comment Share on other sites More sharing options...
Artemis Posted April 29, 2009 Author Report Share Posted April 29, 2009 This is odd, I swear Mickey updated this post today. Either way. Today we grabbed some starter fluid, sprayed it in and it fired up for a second. We got a little light bulb and tried to get it to flash when turning it over... no luck. So the injectors aren't firing for sure. Are both of your injector fuses good? If you mean the small 15-20amp fuses, then yes, we've checked and replaced them. Yep, thats what I was talking about, two 20 amp fuses IIRC. Now, we looked around, and we only found ONE 15amp fuse that was labeled injector. Im guessing these 2 20amps are somewhere else but we can't find them. The one 15amp fuse is in the fuse panel on the passenger side under the hood... right above the ECM. Where would these 2 20amp ones be? Quote Link to comment Share on other sites More sharing options...
Crazy K Posted April 30, 2009 Report Share Posted April 30, 2009 so... the car does run with starting fluid? You have spark? (have you checked all 6 plugs for spark?) fuses can vary can to car and year to year in function.... Imagine that I just discovered that my two 95 cs's have different amp values listed for one of my fuses! check all fuses against your owner's manual, both underhood and inside the car. and.... 3.1mpfi, but what year/model? I know some cars can have an ECM fuse inside. but fuel injector fuses underhood..... so check all. BTW... are you sure your PCM/ECM is functioning? if you have a 3.1MPFI you can do a paper-clip code read to see if any codes are present, and if it works, it at least rules out a totally dead ECM/PCM at fault.

Artemis Posted April 30, 2009 Author Report Share Posted April 30, 2009 Mickey has a 95 GTP just like me. So it has an LQ1. It did start for a second with the starting fluid. And we did confirm that the injectors aren't firing with the test light. Does anyone else have a 95 LQ1 that they can confirm only 1 15amp fuse for injectors? Or are there other fuses elsewhere (other than under the hood passenger side)? Quote Link to comment Share on other sites More sharing options...
Artemis Posted May 4, 2009 Author Report Share Posted May 4, 2009 No one else with a 95 LQ1 that can verify the fuses? Quote Link to comment Share on other sites More sharing options...
Artemis Posted May 8, 2009 Author Report Share Posted May 8, 2009 No one has any idea why the injectors wouldn't be firing? Quote Link to comment Share on other sites More sharing options...
Brian P Posted May 8, 2009 Report Share Posted May 8, 2009 If you're getting just 6-7 Volts to the injectors then likely all fuses are okay. My guess is PCM. If you want to verify it, test for injector signal output at the PCM plugs. Do you have a tech manual? Quote Link to comment Share on other sites More sharing options...

The voltmeter we used to get the 6-7volts might not work that well. But we tried the little 12v light bulb trick and it didn't flash at all.

Brian P Posted May 8, 2009 Report Share Posted May 8, 2009 PCM = ECM in this situation P = Powertrain (newer models like yours that control the engine and transmission), E = Engine control only (you don't have). If you can try another multimeter, then try to verify if the voltage is indeed that low. I've never tried the bulb trick myself so I don't know how quick the flashes are, or how bright the bulb is supposed to get. Quote Link to comment Share on other sites More sharing options...
AL Posted May 8, 2009 Report Share Posted May 8, 2009 The bulb will be really bright and flash over 10 times a second... You will know when its working Quote Link to comment Share on other sites More sharing options...

I do have a spare ECM, i'll let Mickey try it in his car, see what happens. Quote Link to comment Share on other sites More sharing options...
Artemis Posted May 9, 2009 Author Report Share Posted May 9, 2009 It was the ECM, swapped it out with a good one and the car started right up! Thanks for the help guys! Btw, the old ECM was FULL of water and crap. I blame Mickey for not properly closing his hood. Quote Link to comment Share on other sites More sharing options...
